| dc.description.abstract | Teluk Meranti is one of the peatland area in Riau province. Most of these lands have been changed into palm oil plantation, timber plantation, agricultural area and settlement. The aim of this research was to analyze the impact of land use changes on soil physical-chemical characteristics and microbial cell number. Soil samples were taken from eight different locations, namely primary forest as control, secondary forest, rubber plantation (15 monthsyears old), rubber forest (40-60 years old), palm oil plantation (7-8 yearsold), acacia plantation (2-3 years old), corn field, and cassava field. Microbial cell number was determined by spread plate method, employing appropriate media for the growth of bacteria, fungi and actinomycetes. The results showed that the soil humidity, soil temperature, percentage of soil dry weight, water content, soil bulk density and pH ranged from 29,63-55,88%, 27-31,5o C, 14,9-35,5%, 64,9-85,1%, 0,16-0,39g/cm 3 and 3,63-4,00, respectively. The copiotrophic bacterial cell number ranged from 0,6x105-1,8x105 CFU/g soil where the highest population was at the palm oil plantation,whereas the oligotrophic bacterial cell number ranged from 0,5x105-1,4x105 CFU/g soil where the highest population was at the palm oil plantation. The population of fungi ranged from 0,4x105-1,0x105 CFU/g soil where the highest population was at the corn field. The population of actinomycetes ranged from 0,4x105-10,7x105 CFU/g soil where the highest population was at the palm oil plantation. Land use changes caused microbial cell number increased. The results indicated that land use changes influenced the microbial cell numbers | en_US |
